Usability and Interoperability of an Accurate HBIM Architectural Model for Structural Analysis

Abstract. This contribution proposes a multidisciplinary approach to support AEC professionals, such as architects, restorers and structural engineers, in performing structural assessments of historic masonry buildings from a digital model. By integrating advanced 3D modeling tools with historical knowledge and technical data, HBIM enables a detailed and accurate digital representation of historic buildings. Thus, an accurate HBIM model with complex geometric configuration can be used for structural assessment. Currently, public and private administrations in Italy are requesting seismic assessments and structural consolidation of existing buildings. This type of analysis requires appropriate digital models complete with a critical historical building survey describing the transformations it has undergone over time and the construction techniques adopted. The proposed methodology will be tested on a structural element of an Italian basilica of historical-architectural relevance: a pillar of the nave of San Michele Maggiore in Pavia. This research will describe the processes and methods used to use an accurate HBIM model with construction technique in structural analysis software. Digitization of the historical-critical survey using HBIM methodology for cultural heritage is a valuable knowledge tool useful for future structural analysis and consolidation and improvement interventions.
